Maru [420]

Step-by-step explanation:

$3(2.4x+4)=4.1x+7+3.1x\qquad\text{use the distributive property}\\\\(3)(2.4x)+(3)(4)=(4.1x+3.1x)+7\\\\7.2x+12=7.2x+7\qquad\text{subtract}\ 7.2x\ \text{from both sides}\\\\12=7\qquad\text{FALSE}\\\\Answer:\ \text{Zero (no solutions)}.$

Rosetta wants to estimate the percentage of people who rent their home. She surveys 250 individuals and finds that 48 rent their

Andreas93 [3]

Answer:

$0.192 - 1.645\sqrt{\frac{0.192(1-0.192)}{250}}=0.151$

$0.192 + 1.645\sqrt{\frac{0.192(1-0.192)}{250}}=0.233$

Step-by-step explanation:

Information given

$X= 48$ number of people who rent their home

$n= 250$ represent the sample size

$\hat p =\frac{48}{250}= 0.192$ represent the proportion of people who rent their home

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by $\alpha=1-0.90=0.1$ and $\alpha/2 =0.05$ . And the critical value would be given by:
